TNF-α human

半岛bd体育手机客户端 说明

一般描述

TNF-α (tumor necrosis factor α) is a pleiotropic pro-inflammatory cytokine secreted by various cells including adipocytes, activated monocytes, macrophages, B cells, T cells and fibroblasts. It belongs to the TNF family of ligands and signals through two receptors, TNFR1 and TNFR2. The gene is mapped to human chromosome 6p21.3. Recombinant human TNF-α is a soluble 157 amino acid protein (17.4kDa) which corresponds to C-terminal extracellular domain of the full length transmembrane protein.

应用

TNF-α (tumor necrosis factor α) human has been used as a positive control for induction of proinflammatory genes in human intestinal and hepatic cell lines.

生化/生理作用

TNF-α (tumor necrosis factor α) is cytotoxic to a wide variety of tumor cells and is an essential factor in mediating the immune response against bacterial infections. However, it can be a tumor promoter as well as a tumor suppressor. TNF-α also plays a role in the induction of septic shock, autoimmune diseases, rheumatoid arthritis, inflammation, apoptosis and diabetes. It is also associated with mood and anxiety disorders.

Lyophilized from 10 mM Sodium Phosphate, pH 7.4 + 0.5mM DTT.

重悬

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8℃ for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a stabilizer (example 5% Trehalose) and store in working aliquots at -20℃ to -80℃.
